Title: 1930 30 U Schrader Valve, what is correct?
Post by: hursst on April 30, 2025, 10:16:21 AM
Hello,

  What should the Schrader valves look like on a 1930 Plymouth 30U with wire wheels?  The attached photo is what I have on there currently.  Is this correct, or should it be something slightly more modern, but not what we have today?  Any knowledge or photos of what is known to be correct are greatly appreciated!  -Chris

Sorry I've been off the board for a while. This is the type I have on my '29 wood wheels.

By 1930 the use of valve stem covers which were usually used on tubes with metal valve stems was phasing out.  Plymouth never used them in 1930 if the fact that they are not listed in the Plymouth parts catalogue can be taken as evidence. A rubber stem tube with a cap was all they used.  My car has dual side mounts and one of them was original to the car according to the original owner I bought the car from in 1962 and that's what it had.  By the way, the term "schrader valve" just refers to the valve that is screwed into the valve stem.  That said, there's no reason why you can't consider the valve stem covers you have to be an after market accessory and use them if you like the way they look. Personally, while I don't have them on my 30U, I like the way they look and they certainly dress things up a bit.

I agree with Rusty! They look good & period correct and may even be beneficial if they keep the stem centered in the wheel better. Unlike the Model A it's  hard to track down what is 100% correct on these cars. if you got em & like em run em!

I believe this is a photo of a wheel for a 28 Plymouth at the Chrysler museum
